A Hyper-V Bug?

Brien Posey Brien Posey Profile: Brien Posey

Lately, I have been really frustrated with what appears to be a bug in Hyper-V. Unfortunately, I can’t seem to find any references to it on the Internet, so I am beginning to wonder if this is really a bug, or if it is something related to my own unique environment.

What happens is that the registry routinely gets corrupted on virtual machines that are running Windows Server 2003 R2. I will be working on a VM with no signs of trouble, reboot the VM, and receive a message stating that the registry was corrupted. The crazy thing is that there doesn’t seem to be any rhyme or reason for the occurance. I have seen it happen to freshly installed copies of Windows as well as VMs that have been running for weeks. The interesting thing is that it is always the same registry key that becomes corrupted (HKLM\Software).

Over the last couple of months, this has started to become a major issue for me. I have lost dozens of hours of productivity to rebuilding lab VMs. I just wanted to put this out there and see if anyone else has experienced this problem.
